Experiments with different K. pneumoniae infecting Galleria mellonella. A Survival rates of NTUH-K2044 and 7 strains K. pneumoniae without these four virulence genes, + PBS empty control and blank control. Survival rates of 24 strains containing these four virulence genes; B 6 strains were high virulent, with a survival rate of 50% or less within 72 h; C 14 strains showed low virulence with a 72-h survival rate greater than 50%; D 4 strains were nonvirulent with 100% survival at 72 h. NTUH-K2044 carried these virulence genes: iroB, iroC, iroD, iroN, iucA, iucB, iucC, iucD, iutA, rmpA and rmpA2
